Fellow Isogeochemists,

        Have there been any publications describing the application of  stable
isotopes to tease out aquatic food chain relationships in the tropics?
Most of the isotope work describing food chain relations seem to be in
temperate climates or in the open ocean.  Of particulalate intereste are
shallow water systems, where there is not much distinction between the
benthic and pelagic food webs and not much in the way of thermoclines or
nitriclines.
